Note that I've seen the pattern of providing sin, cos and atan (but not other trig functions) in other libraries and programming languages. And the reason for this (that so far as I can tell no one has yet said) is simple: those functions are defined for all values of their argument. tan isn't. arcsin and arccos aren't.

Not that it's necessarily a very good reason, mind you.
